DEVICE FOR PRESERVING EGGS.

SPECIFICATION forming part of Letters Patent No. 333,636, dated January5, 1886.

Application filed September 19, 1885. Serial No. 177,594. (No model.)

To all whom it may concern;

Be it known that I. OWEN W. JONES, a citizen of the United States,residing at New Oambria, in the county of Macon and State of Missouri,have invented anew and useful Improvement in Apparatus for PreservingEggs, of which the following is a specification, referenee being had tothe accompanying drawings.

This invention has relation to improvements in apparatus for preservingeggs; and the novelty consists in the peculiar construction,combination, arrangement, and adaptation of the various parts forservice, substantially as hereinafter fully set forth, and specificallypointed out in the claims.

The invention is especially designed as an improvement in that class ofegg-preserving apparatus shown in patent to T. Lee, No. 269.866, datedJanuary 2, 1883, in which a main frame having ways, a sliding framemounted thereon, and a series of independently-journaled rollers rotatedby the sliding movement of the frame are employed. The rollers in thisframe projected below the lower edges of the sliding frame, and wererotated by frictional contact with the ways. This construction isobjectionable, for the reason that considerable material was necessaryto properly construct an operative device, and care had to be taken toproject the rollers at an equal depth below the plane of the slidingframe to cause an even and steady movement of the sliding frame, whichwas thus wholly supported by the independently journaled rollers; andone of the objects of my invention is to provide an open frame whichshall be very simple and light and cheap and easy in its construction,and which shall provide a track or hearing for asliding frame arrangedabove the first or lower frame, thus making a series of egg-preservingframes or trays.

In this class of devices it is of vital importance that the egg shall begiven a rolling or rotating movement very gently for the purpose ofpreventing the settlement of the yelk through the white of the egg, andthe egg is thus preserved.

Another object of my invention is to provide means whereby asemi-revolution can be given to one half of the eggs, and by means ofadjusting devices the remaining half can be turned, or only a quarter oran eighth of a revolution given to such eggs, as may be desired orrequired; and a further object of the invention is to provide meanswhich shall be very simple, strong, and durable in construction,thoroughly effective, easy and positive in operation, and to cheapen themanufacture.

I have shown an embodiment of my invention in the accompanying drawings,which form a part of this specification, in which- Figure 1 is a planview of my improved eggpreserving apparatus. Fig. 2 is an elevationthereof showing two sliding trays. Fig. 3 is a longitudinal section onthe line a: a: of Fig. 1. Fig. 4c is a diagram showing the manner inwhich the eggs are rotated to any desired extent, and Fig. 4; is asimilar diagram.

Like letters of reference in the several figures of the accompanyingdrawings denote corresponding parts.

Referring by letter to the drawings, A designates the main supportingframe; B, the sliding frames mounted on the main frame and arranged inseries one above the other; and G designates a series of rollersindependently mounted or journaled in the sliding frames and adapted toreceive the eggs which are to be preserved, the particular detailedconstruction of the several parts of which I will now proceed todescribe.

The main frame A comprises vertical supporting-uprights A, preferablyfour in number, to form a square or rectangular frame, said uprightsconnected on their inner faces by longitudinal beams or strips A notchedat their ends, as at a, and providing a track or way upon which thesliding frames B are mounted.

For the purpose of adding strength and rigidity to the main frame crossbars or braces a are secured to the uprights by screws, bolts, or othersuitable fastening devices.

Each sliding frame B comprises two side pieces, 7), arranged to bear onthe inner sur faces of the trays or ways A", and having their loweredges arranged below the plane of the upper edges thereof, and adaptedto serve as guides in the sliding to-and-fro movement of the frame, aswill be readily understood. The rollers G are arranged within the planeof the side pieces of the sliding frame, and are journaled therein,independently of each other, at their ends by means of pins or studs 0,which pass through or project beyond the said side pieces of the slidingframe and receive or have secured upon them bearing or supporting wheels0, which roll or bear upon the track" or way A and serve to maintain orsup port the frame B thereon and keep it in a nor mally-horizoutalposition. The rollers O and their bearing-wheels G are of the same size,and when the wheels are revolved by frictional contact with the track orway they are rotated at the same speed, and thus revolve the rollers Gand the eggs placed in the space between two adjacent rollers evenly anduniformly without subjecting said eggs to any injurious jars orshocks.

Iattach especial importance to supporting the frame and rollers thereofupon the bearing-wheels O, and to arranging the side pieces, 12, of thesliding frame below the plane of the upper edge or surface of the trackor way, as by such construction the frame serves as a guide in itssliding movements, and the friction-rollers or bearing-wheels serve asan efficient means for producing the rotary movement of the rollers O,and being of the same size they are rotated at the same speed or rate. IParticular care or pains is not required in journaling the rollers andin arranging them in the sliding frame, as the bearing-wheels serve tosupport the sliding frame, and at the same time to rot-ate the rollers Oand the eggs placed thereon.

In the upper edge of one of the side pieces of the frame B, I out orform a recessed portion, d, to provide two shoulders, 11, which serveaslimiting-stops to the longitudinal play of the sliding frame. Astop-pin, D, projects across the plane of cut-away portion of the sidepiece of the sliding frame and comes in contact alternately with one ofthe shoulders (2' when the sliding frame is moved back and forth by handor otherwise. The stop-pin D is detachably connected to or fitted in oneof a series of holes, 6, in a stop block or piece, E, secured in anysuitable or preferable manner to one of the supporting-uprights A of themain frame. The length of the recessed portion d, or the distancebetween the shoulders d,is such that the frame B is permitted to move asufficient distance to rotate the rollers and bearing'wheels to revolvethe eggs a half-revolution, the stoppin D coming in contact orengagement with the stop-shoulders d alternately, as described above.

I will now proceed to describe the peculiar function of the stop-pin D,which is adjustable so as to fit one of the series of holes 6 in thestop-block E, reference being particularly bad to Fig. 4 of thedrawings. In such Fig. 4 but two of the rollers O are shown in section,and a dotted diagram, showing the egg in its various positions when thestop-pin is adjusted to the first holes 6 in the stop-block. The diagramof the egg is lettered F, and the figures 1 and 2 indicatediametrically-opposite points in the circumference of the shell thereof.For the sake of illustration I will assume the points land 2 to lie in ahorizontal line with each other. When the frame is at one of its strokesor sliding movement, and whenit is moved in the opposite direction, asshown or indicated by the arrow in Fig. 4, the rollers O are rotated andthe eggs thereon are revolved by frictional contact therewith a half orsemi revolution, as shown in the dotted-line position to the leftof Fig.4, the position of the points 1 and 2 being relatively changed orreversed thereby, and when the frame is moved back to its first positionthe eggs are also moved or revolved to their first position,shown infull lines. To rotate or bring the remaining half of the eggs uppermost,the pin D is adjusted to the second or an intermediatehole, e, in thestop-block, as shown in the diagram of Fig. 4, thus changing theposition of the points 1 and 2, so that they lie in a vertical plane, asshown, whereby, when the frame is moved back and forth, the remaininghalf of the eggs is brought uppermost and the eggs are subjected to achange in the position, which is so necessary to the successfuloperation of their preservation. By having the cross bars or beams Aarranged one above the other and the upright posts A a track or way forthe upper sliding frame or tray is provided, and it will be understoodthat any desired number of tracks or ways and sliding frames may beemployed The sliding eggcarrying frames are provided with handles of anysuitable construction for operating them by hand or otherwise.

In lieu of the recessed portion (1 to provide the stop-shoulders d,removable pins may be secured to the frame to provide the stops, or aslot may be cut therein, and different means for holding the stop-pinmay be employed, and the shape or form thereof can be varied.

Various slight changes in the form and proportion of parts and detailsof construction can be made without departing from the principle orsacrificing the advantages of my invention, the essential features ofwhich will be readily understood from the foregoing description, takenin connection with the drawings. a

By adjusting the pin D to the last or third hole in the stop-block thepositions of the figures l and 2 of the eggs are reversed, and when theframe is operated they successively assume the various positions of eachother in the manner shown in Fig. 4, and by increasing the number ofapertures in the stop-block E the eggs can be so adjusted as to bringevery point in their circumference under action, as will be very readilyunderstood.

I am aware that heretofore it hasbeen proposed to limit the movement ofthe sliding egg-carrying frame by the same coming in contact with anabutment on a bed-frame, and I hence I disclaim such construction; butin my improved apparatus I employ a stop which can be adjusted to varythe movement or stroke of the sliding frame. By means of this adjustablestop the distance which the egg is turned can be regulated and is underthe immediate control of the operator, thus obviating the liability ofthe yelk settling through the albumen. It is well known that in order toproperly preserve eggs they should be turned a semi-revolution onceinevery twentyfour hours; but in my deviceI provide means whereby the eggcan be turned three-quarters of a revolution, so that the yelk lies atright angles to the plane at which it lies before the frame is operated.This construction is more apparent and readily understood from Figs. 4and at of the drawings.

Before operating the frame the diametricallyopposite points 1 2 in theshells of the eggs lie in a horizontal plane, as shown in Fig. 4. Thestop is then adjusted in one of the apertures e, so that when the frameis moved the eggs are given three-fourths revolution, so that when theframe comes in contact with the stop the points 1 2 in the eggs thereonlie in avertical plane, as shown in Fig. 4?, and by this peculiararrangement the yelk is suspended in the albumen at right angles to theposition which it occupies before the frame is operated, and the eggsare preserved for a longer period of time.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In an egg preserving apparatus, the combination of an open frame, A,a sliding frame, and a series of independently-journaled rollers, O,mounted in the sliding frame and having their bearings projected beyondthe sliding frame, and provided with bearing-wheels G, adapted to bearon the track or way of the main frame and support the sliding frametherein, substantially as described.
